MACHINE r012. ROUGH-ROUNDING AND LAsrmesmcnEn-nown SHOES.

in connection with the accompanying draw.

ing, is a specification, like characters on the drawing representinglike parts.

This invention has for its object to provide a novel machine forsimultaneously rough rounding and lasting stitched-down shoes, thusperforming at one operation the lasting of the upper and the trimming ofthe sole. I

Features of the invention consist in means to force the upper into theangle between the side of the last and the projecting margin of thesole, means for pressing the marginal portions of the upper and soletogether thereby toperform the lasting operation, and means operatingsimultaneously to trim the edge of the sole at the required distancefrom the last. 1

In the presentmachine the shoe being operated on is held against a worksupporting element which also functions to tuck the upper into thecorner between the last and will be now described, after which the novelfeatures will be claims.

In the drawings, Figure 1 is a side view of pointed out in the appendeda machine embodying my invention.

Fig. 2 is a front view thereof.

Fig. 3 is a top lan view.

The principal parts of the device comprise a work supporting member qrwork-guiding Specification of Letters Patent; Patented Nov, 29, 1921,Application filed October 13, 1920. Serial No. 416,605

, member against which'the projecting portion of the sole of the shoe isheld and which also operates to force the upper into the angle betweenthe side of the last and the projecting margin of the sole, a presserelement or beater constructed to act on the under face of the sole atthe margin sole and press or beat the marginal portions of the sole andupper portions together, and a" trimming knife which operates to trim orrough round the sole.

These parts are suitably mounted upon a frame 5 which may have anysuitable shape adapted for this purpose. V

i The work-holding or work-guiding device comprises a plate 6 secured tothe frame 5 and a member 10 in the form of a truncated cone whichoverlies the plate 6 and cooperates therewith to support and guide theshoe and which also by its shape operates to force the upper into theangle between the side of the last and the projecting portion of thesole. In Figs. 1 and 6 I have shown a portion of a shoe on a last, 1indicating the last, 2 the upper of the shoe, 3 the sole there} of and 4the marginal portion of the upper which is to be stitched to themarginal portion of the sole. -In operating on a shoe.

the latter is held, as shown in Figs. 1 and 6 with the portion thereofprojecting beyond the last placed against the work-holding device, andthe operator will move the shoe relative to the work holder so that thelatter will follow around the last and in doing so the work is pressedagainst the member 10.

Situated beneath the member 10 is a presser elementor beater 7 which isreciprocated vertically and which cooperates with the elements 6 and 10to press together the marginal portions of the upper and the sole. Thetrimming knife, by which the sole is trimmed, is indicated at 33 andthis is also arranged to have a reciprocating movement.

The beater or presser member 7 is yieldingly mounted on a slide orcarriage 8 which is sli'dable vertically on ways 9 formed on the frame5. This slide 8 is shown as having thedove-tail ways 29 formed thereinand the beater or presser member 7 is provided with an extension 28which slides in the ways 29. through which extends an adjusting screw.30, that is screwthreaded into thelower end Said extension has a hub 49'of the carriage 28. Said screw has a hand wheel 31 on its lower end anda spring 32 encircles the screw 30 and is confined between the hub 49and the hand wheel. Said spring thus makes a yielding support for thepresser member 7. The slide or carriage 8 is reciprocated vertically onthe Ways 9 and for this purpose said slide 8 is provided with rack teeth23 which mesh with teeth 22 formed on one end of a lever 20 pivoted tothe frame at ,21, the other end of said lever 20 being connected by alink 19 to a crank pin 18 carried by a shaft 15 which is rotativelymounted in the frame. Said shaft is shown as having fast and loosepulleys 16, 17 thereon by which it may be driven.-

The presser member 7 is preferably so adjusted by the screw 30 that whenthe slide 8 is raised the presser member will engage the under side ofthe sole before said slide reaches the upper limit of its movement, sothat during the final upward movement of the slide the spring 32 will becompressed thus producing a yielding pressure against the sole.

The trimming knife 33, by which the sole is trimmed, is secured to theslide 8 and by such upward movement of the slide the trimming knife cutsthrough the sole, thereby trimming the latter, the plate 6 constitutinga cutting bed against which theknife acts.

In Figs. 1 and 2 the slide is shown as raised and the beater 7 ispressing against the sole and the cutter 33 has cut through the edge ofthe sole. When the slide is at the lower limit of its movement theexpanding action of the spring 32 will raise the presser member 7relative to the knife so that the face of said presser member will beabove the cutting edge of the knife. When the carriage 8 moves upwardlytherefore, the presser member 7 is first brought against the bottom ofthe sole and as the carriage continues its upward movement the spring 32is compressed and the knife is brought into position to cut through thesole and trim the latter, as shown in Fig. 1. As the shoe is movedaround the work support, 6, 10, the member 10 forces the upper into thecorner between the side of the last and the projecting portion ofthesole, the beater or presser member 7 presses the marginal portions ofthe sole and upper together and the cutter trims the sole, thusperforming the rough rounding operation. I

It will be noted that when the cutter comes into action the marginalportions of the sole and upper are clamped between the work support andthe presser member 7 so that the shoewill be firmly held during eachcutting operation.

In the present embodiment of the invention the member 10 is shown ashavinga reciprocating motion parallel to the sole. This is accomplishedby mounting the member 10 on a slide 11 which is provided on itsunderside withdove-tailed ways 12 which receive the uiding member 13formed on the frame 5. aid slide 11 is connected by a link 24 to a crankpin 25 carried on the end ofa shaft 26 which extends parallel to theshaft 15 and is geared thereto by suitable gearing 27, which isconstructed so that the two shafts 26 and 15 rotate at the same speed.

The member 10 is provided on its under face with a recess to receive theplate 6, said recess being sufiiciently larger than the plate to permitthe necessary reciprocating movement of the member 10 relative to theplate. This member 10 is in the form of a truncated cone and is freelyrotatable in the slide.
